SmartPlug vs. Twist Lock


RV and boat owners have long relied on Twist Lock style connections for powering their rides. For years, it has been the best option for connecting to shore power. It's been reliable, but most know it's not without disadvantages:


Twist-Type Design Problems

  • Curved pins make minimal surface contact, increasing the amount of heat generated
  • Locking ring can be prone to breaking, cross threading, and stripping out
  • Faulty locking ring puts strain on the connection
  • Wear and debris can loosen the fit, further decreasing surface contact
  • Circular plug shape isn't user friendly and takes some awareness of the orientation of the pins to insert correctly

SmartPlug's connector addresses each of these concerns and does all of the heavy lifting.


Locking arms grab the inlet, a clamp inside the plug body holds the cord, the inlet cap snaps to the top while in use, and the integrated seals weatherproof the connection. This helps prevent the wiggly, dirty connections that increase electrical resistance, which creates potentially dangerous heat.


Since it uses a square plug face, SmartPlug is able to use flat pins which create far more surface contact, further reducing the risk of high heat and electrical arcing. The square shape and flat pins also make it easy to plug in - no more twisting or guessing if the pins are lined up correctly.

Video Transcript for All You Need to Know About the SmartPlug RV Power Inlet

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the SmartPlug 30 amp RV Power Inlet. Now, this inlet here will let you plug in your SmartPlug cord to power your RV or your boat. You can see it is a 3-prong male inlet, and it'll accept the SmartPlug 30 amp female connectors which we do sell separately on our website, and I did wanna pop up an insert just to show you, there's one of those connectors on that cord there, and that's what'll plug right into here. Now, this inlet has a multi-point lock system for secure connection of that female connector, so when you plug that in, you'll notice there's cutouts here at the bottom on each side, so when it plugs in, it'll lock it into place to keep it connected. It is a straight-in, single-step operation, means no more twisting or fiddling with locking rings, and this design or the plug shape will take any guesswork out of how you connect it, so it's very simple to use even in the dark.

The flat electrical pins, they'll give you 20% more contact area compared to the curved pins and twist locks, and this will reduce the heat that's caused by electrical resistance. The cover on this, you can see the cover, this inlet cover will snap down onto the plug body, you can see right here, once you plug your plug in, this will go down over it and help hold that plug into place, helps reduce any strain on the cable, and it helps stop the plug from being yanked out accidentally. And if you noticed on the top of that cover, there's a rubber seal here that'll go down over this and help keep it safe from any elements when it's not being used. Now, they do use high quality materials which will hold up at extreme climates or out on the water. They use marine-grade stainless steel components that'll hold up season after season, they use nickel-plated brass electrical pins and tinned wires to resist corrosion, and all the plastics on this are UV and heat resistance.

It is a very easy installation, only requires four screws and three wires connection, and it is size to fit standard inlets, so you can use the same screws and holes. If you noticed, it does include this nice rubber gasket, and this will help seal the inlet when it's installed. So basically, what you'll do is put this up here, and then when you go to install that, that'll help seal it. This is a nice gray color, it is made in the USA. Few specs on this, amperage on this is 30 amps, voltage, 125 volts.

But that should do it for the review on this SmartPlug 30 amp RV Power Inlet..

Quality product. Easy installation



by:

On time and exactly what I needed



by:

Easy process, glad I bought thru etrail er.com.



by:

Fantastic product and company

I found the installation of the inlet easy and the modification of the connector very easy. The instructions were very easy to follow and very comprehensive.

The only issue was the rear cover (pictured) for the inlet could not fit at the front location of may 2019 Airstream Flying Cloud 27 ft. FB. I also installed the cable port.



by:

The SmartPlug installed great and after a year of heavy use continues to perform perfectly! Electrical hookups are now quick and positive with solid connections!



by:

This Smart plug inlet plug is true to size. I've used the Smart Plug system on other RVs and am familiar with the better contact area. I was delighted to see that this plug fit inside the connection center of my campervan, and still be able to close cover with no bulging.



by:

The old style RV plugs are prone to have connection problems which causes melting of the unit. That happened to me in below freezing weather and we lost power to our trailer. This new plug will not have that problem. It fits together solidly and I don't worry about any loose connection. I have seen that the SmartPlug is now standard equipment on Airstream trailers. That's quite an endorsement. You Cann't go wrong with the SmartPlug system.



by:

Ordered this to replace our current plug on our ‘08 airstream 28’international ccd. I apparently didn’t understand that the kit didn’t come with the male plug as well-the pic kind of confused me. I reached out to smart plug and went above and beyond to help me get what I needed to get it going. Can’t say enough about smart plug-excellent customer service!!



by:

Product arrived in a timely manner, printed instructions were reasonably good & informative. Communications with etrailer were outstanding!



by:

This plug is so much better than the OEM twist lock plug! It wasn't difficult to install and appears to be a quality item.



by:

Easy to install and so much better of a system to hook up power, plug and go. Highly recommend the Smart Plug for safety and ease of use, plus looks good too.



by:

This was the best upgrade! We had issues with our last plug pulling down, which eventually cracked the plastic on the box. After this install we have never had an issue and it’s a more secure and snug fit. After a year, it’s held up to our full-time travels very well. I’d highly recommend.

Here’s the video we did on this product: GAME CHANGER! RV SMART PLUG INSTALL.



by:

This product completely fixed all our RV's electrical issue caused by a loose connection from the traditional power cord.



by:

After a year I really like this SmartPlug system. Was easy to install. And it works great.



by:

This is a great upgrade. Our 50amp cord and inlet was arcing and was very dangerous. This product arrived on time, instructions were great and this is a complete game changer. It's a better connection no issues and easy installation. Took me about 30 minutes tops.



by:

I have on several occasions experienced times when my electricity inside our RV wasn't working. It would inevitably be because the connection from shore power to the camper was loose. I just installed my new SmartPlug today and already feel confident in the connection. Purchasing from etrailer was easy and the product shipped in a timely manner.



by:

etrailer kept me in the loop on the backorder of the black SmartPlug, I understood the supply chain, but it was nice to be updated on the timeline for shipment. So nice for a company to keep you in the loop without having to chase the details!



by:

When saw this of course I said I wanted it. This make hooking up a lot easier and I feel more secure about the electrical connection. Now my friend wants me to change his. The conversation was very simple.



by:

I really like the SmartPlug! I kept noticing the old plug would turn sometimes in the socket and just about unplug itself. The SmartPlug is always secure and easy to unplug when you are ready.



by:

Easy to Install. Clear instructions but you can also find install videos on YouTube. Stainless cost slightly more than the plastic version but looks great on my Airstream.



by:

Replaced the "standard" connection and this one is sooo much better! I would do this again with any new motor home or trailer.



by:

The Smart Plug is a quality upgrade to our Airstream. It looks good and was an easy quick install.
